Glucose Serum is a fasting blood sugar test is used to measure glucose levels in the blood. It is used to help in screening for and diagnosing diabetes mellitus; evaluating carbohydrate metabolism disorders including alcoholism; evaluating acidosis and ketoacidosis and evaluating dehydration, coma, hyperglycemia and hypoglycemia.
Fasting Insulin levels may be useful predicting susceptibility to the development of type II diabetes, though C-peptide has mostly supplanted insulin measurement for this role. The measurement of insulin levels is not included in The American Diabetes Association recommendations for diagnosis.
Hemoglobin A1c (Glycohemoglobin) test evaluates the average amount of glucose in the blood over the last two to three months. This is done by measuring the concentration of glycated (also often called glycosylated) hemoglobin A1c. Hemoglobin is an oxygen-transporting protein that is found inside red blood cells (RBCs). The predominant form is hemoglobin A. In 2010, the American Diabetes Association affirmed the decision of an international expert committee recomendation to use the A1c test to diagnose diabetes with a threshold >/= 6.5%. Point-of-care A1c assays are not sufficiently accurate at this time for diagnostic purposes.
Vitamin D 25-Hydroxy tests are used to determine if bone malformation, bone weakness, or abnormal metabolism of calcium (reflected by abnormal calcium, phosphorus or PTH tests) is occurring as a result of a deficiency or excess of vitamin D. Because vitamin D is a fat-soluble vitamin and is absorbed from the intestine like a fat, vitamin D tests are at times used to monitor individuals with diseases that interfere with fat absorption, such as cystic fibrosis and Crohn's disease, to assure that they have adequate amounts of vitamin D. Vitamin D tests are used to determine effectiveness of treatment when vitamin D, calcium, phosphorus, and/or magnesium supplementation is prescribed as well.
Vitamin D sufficiency, along with diet and exercise, has emerged as one of the most important preventive factors in human health. Hundreds of studies now link vitamin D deficiency with significantly higher rates of many forms of cancer‚ as well as heart disease‚ osteoporosis‚ multiple sclerosis and many other conditions and diseases. Foods rich in Vitamin D include: milk fortified with Vitamin D, fish, egg yolks, liver and cereal fortified with Vitamin D.
